I think "M-g" works in the summary buffer in precisely the same way as
in the groups buffer.

can't answer this one.

I have 

(setq gnus-parameters
      '(("maildir"
         (expiry-wait . immediate))))

in my .gnus.el, where "maildir" is a regular expression that happens
to match all my imap-folders. 
(Alternatively, you could put all your mail-folders in a topic, and
set the expiry-wait option for the whole topic...)
